IMPROVEMENT In TNNSR- SOLE.

TO YALL WHOM IT MAY CONCERN: v p

Be it knownl that I, A. WEBSTER,.of Sandisehhin the county of Berkshire, 'andi State of Massachu setts, have invented a new and improved Inner Sole; andJI do hereby declare that the following is a full, clear,

.and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification. l

This invention relates to a new andimproved method of constructing inner soles for boots or shoes, whereby the same are more cheaply mad.e,`are more durable, andarerendered impervious to water. It consists of one or more pieces of' wood, or a thin piece of wood und a piece of felting-or cloth, lbetween which is a thin layer of gutta percha or rubber, by the warming of; which all the several layers are rmly connected together. In the accompanying plate of drawings- M Figure 1 represents-a plan view of the parts of which-'the sole is composed in position tobe placed together.

' 4Figure 2 represents a. view of the edge of the sama-thepart being partly separated to show the inner or getta-perche'. layer.

Similar letters of reference indicate corresponding parts.

A is a thin sole-shaped piece of wood. C is anotherrtb'in sole-shaped piece of Wood, or a sole-shaped piece of cloth or felting.4 B is a thin fabric, of ,gatta percha, another substance with-like quali ties.` Upon the thin piece of wood or veneering A is laid a thin-layer of guttaipercha, or other substance having like qualities, B,

of like shape and size, and upon said layer B another like` piece of wood or'veneeri'ng, or belting or cloth, or

other suitable material, which, being pressed together and heated, the layer of gatta. perche. or rubber, or other substance, B, is softened, and adheres to the sides of the parts 'A and C, thereby oemen'ting them rmly together".

into asole or other article, and rendering the same 'impervious to water.v

Constructed as above described, it formsY a' light, thin, and durable substance, impervious to water, suitable for the inner soles of boots or shoes, or for' any purpose where the above qualities are required.

I claim as new, and desire to secure by Letters Patent- As a new larticle of manufacture, an inner sole, composed of two strips of wood, A C, seoured together by means ofthe gatta-perche. strip B, heated, and placed between-them, as herein shown and described for the ur oses eoiiied.
